Active clinical trials for "Emergence Delirium"

The purpose of this study is to determine whether Rivastigmine is effective for the prevention of postoperative delirium in patients undergoing cardiac surgery.

Preoperative anxiety is characterized by subjective feelings of tension, apprehension, nervousness and worry. In children, preoperative anxiety is reported to result in postoperative negative psychological effects, including nightmares, eating problems and increased fear of doctors. Previous studies have assessed anxiety in children during the preoperative period and the effects of premedication and parental presence. Midazolzam has been shown to reduce preoperative anxiety in children but post operative recovery maybe delayed for children undergoing a short operative procedure. Distraction may be particularly helpful in children ages 6-12 as these children are curious about their environment. An association between preoperative anxiety and emergence agitation has been suggested. Emergence agitation in children is not well understood but is a frightening experience for child and parent. A previous study demonstrated the efficacy of hand held video games used as an interactive distraction to allay preoperative anxiety. The purpose of this study is to treat preop anxiety with premedication, or video game and to evaluate the impact of these interventions on the incidence and severity of emergence agitation.

The purpose of this study is to determine whether preoperative administration of Rivastigmine prevents the incidence of postoperative delirium in patients undergoing major surgery as well as postoperative cognitive dysfunction.

Proper preoperative sedation can reduce patients' anxiety, enhance patients' cooperation and reduce perioperative complications. The investigators would explore the sedative effects of dexmedetomidine (DEX) with the administration of oral, intravenous and nasal drops, and detect DEX blood concentration in 15 participants, respectively. Pharmacokinetic parameters are detected at 8 time points ( before DEX administration, 10 min, 20 min, 30 min, 45 min, 60min, 90min and 120 min after administration). 3 ml arterial blood was collected at each time point. The blood samples are detected by mass spectrometer. The aim of this study is to investigate appropriate administration time and route for DEX sedation.

Emergence delirium is a common complication in children after anesthesia. The incidence of emergence delirium is reported upto 50%. Prevention of emergence delirium in children is important not only for the patient safety but also for the satisfaction of the parents. Midazolam is the most commonly used medications for prevention of emergence delirium. However, it might lead to delayed awakening from anesthesia and respiratory depression. In this study, the investigators will evaluate whether dexmedetomidine can be effectively and safely administered for prevention of emergence delirium in children compared to midazolam.

This study examines the potential link between deep levels of anesthesia and delirium.

The purpose of this study is to find out whether postoperative delirium can be more properly prevented by the combination of determined preventive agents in past studies. Further on the investigators measure pre- and postoperative cortisol, neuron specific enolase (NSE) and S-100beta levels.

Postoperative delirium (POD) - a temporary state of confusion - is a frequent complication of surgery, which most commonly occurs in elderly patients. A tablet computer application that may assist preoperative risk screening for POD was developed at the University Hospital Basel in 2014. This study aims to investigate whether the computer program may assess the risk of a patient to develop POD.

The aim of this retrospective study was to detect the effectiveness of 1µg/kg oral dexmedetomidine premedication on preoperative cooperation and emergence delirium of the the young children underwent complete dental treatment.

Emergence delirium/emergence agitation (ED/EA) is a behavioral phenomenon of unclear etiology consisting of short lived behavioral changes that can be both traumatic to families and pose a safety risk to patients and staff. ED is characterized by a variety of presentations, including crying, excitation and agitation, that occur during the early stage of recovery from general anesthesia, generally in the first 30 minutes. Emergence delirium occurs in children of all ages following an anesthetic with halogenated agents (e.g. sevoflurane/isoflurane) with or without having undergone a surgical procedure (e.g. MRI patients). Presently, the treatment for ED is to revert the patient back to a hypnotic state mainly with sedatives so that they may "reset" themselves postulating that by re-inducing a hypnotic state, the brain has time to resolve this issue. The hypothesis of this study is that during ED, there is failure of organized EEG activity, especially alpha wave activity and that by enhancing alpha activity, the incidence of ED may be reduced without the need for additional pharmaceuticals which may be costly, delay recovery and are not without adverse effects specifically cardiopulmonary depression through the use of blue monochromatic light.
